FRAMEVFOR DOORS OR WINDOWS.

SPECIFICATION forming part of Letters Patent No. 258,839, dated May 30,1882. Application filed December 2B, 1881. (No model.)

To all whom it may concern:

Be it known that I, CHARLES H. WILLsON, a citizen of the United States,residing at Mount Vernon, in the county ot' Westchester and State of NewYork, have invented new and useful Improvements in Frames forDoors orWindows, cf which the following is a specification.

This invention relates to improvements in door or window frames; and itconsists in the combination, with the surrounding frame ot' a door orwindow, of a jarnb or lintel composed ot' a movable section, springsacting on the movable section, suitable stops for limiting the. motionof said movable section, and bevv eled edges on the movable section andthe door or window, respectively.

The invention is fully illustrated in the accompa-nyin g drawings,inwhich- Figure 1 represents a face View of a door provided with myframe. Fig. 2 is a transverse section of the same in the plane w x,Figs. l and 4. Fig. 3 is a vertical section in the plane y y, Fig. 4.-Fig. 4 is a partly-see' tional i'rontview of the'door. Fig. 5is atransverse section of the same in' 'the plane e e, Fig. 4. Fig. 6 is aview on an enlarged scale -v of a part of the construction shown in Fig.2,

in order to more clearly illustrate the same.

Similar letters indicante corresponding parts. In these drawings, theletterA designates a door, which swings on hinges a a in the casing B. Ois thejamb, and D the lintel. The frame B is provided with a verticalgroove, d, to receive a tongue, e, projecting from the movablejamb-section b, and the latter is provided with l a vertical groove, f,to receive a tongue, g,

projecting from the frame B, so that thesaid frame and the movablejambsection b are so connected that no aperture appears in the face ofthe frame. The movable jamb-section b is subjected to the action ofsprings h It, which may be made in the form shown in Fig. 4, or in anyother form suitable for the purpose, and in the frame B are securedstops z' fi, which engage with grooves j j in the movable jamb-section,so that the latter cannot be forced inward by the springs 1th beyond thedesired limit. The inner edge, 7c, of' the movable section bis beveled,Figs. 2 and 6, and the corresponding edge, l, of the door is alsobeveled, so that when the door is being closed the movable seci tion bis gradually forced back, and after the door has been closed the twoedges k and l are held in close contact by the action of the springs hh.If any shrinkage takes place in thedoor or in its casing, the movablesection b of the frame adjusts itself automatically, and the bevelededges lc l remain in close contact.

The lintel D is provided with a movable section, n, and the section mmay be connected with the lintcl in the same manner as above describedfor the jamb-section b andthe frame B, or they may be connected byproviding the lintcl D with dovetailed cleats o, Fig. 5, which engagewith corresponding guides, p, in or'on thev movable section u, and whichare provided with suitable stops to limit the forward motion ot' saidmovable section. The springs h* It* act on the movable sections, andthese springs have the spiral form; but they maybe made in any othersuitable form. The cleats o and vguides p may be formed of metal, ifdesired.

The edge q ot' the movable section n of the lintcl is beveled, (see Fig.3,) and the corresponding edge, r, of the door is also beveled, so thatin closing the door the movable section n is forced back gradually, asabove described.

It' the edges k and q of the movable sections b and n, respectively, andthe corresponding edges ot' the door or window, are not beveled,

my frame cannot be used with advantage for doors or windows which swingon hinges.

-What I claim as new, and desire to secure by Letters Patent, is-

l. The combination, with the surrounding frame ot' a door or window, ofa movable section,.b, both the said section and the frame being providedwith tongues cg and grooves d -respectively, the stops it', and springs7L h, substantially as and for the purpose set forth.

2. The combination, with the surrounding frame of a door or window, of ajamb or lintel composed of a movable section, b, springs h h, acting onthe vmovable section, suitable stops for limiting the motion of saidmovable sec tion, and beveled edges 7c Z on the movable section and dooror window, respectively, substantially as and for the purpose shown anddescribed.

In testimony whereof I have hereunto set my hand and seal in thepresence of two subscribin g witnesses. Y
